Well, I agree with everyone on this. Regular check-ins are a must.  
And that's exactly the reason why subversion has branches :)

Depending on how you use your branches, you might require people who  
have a larger task to work on a separate branch and then merge when  
they're done. Personally I have most of the developers working on the  
main trunk, and maintain separate 'production' branches, because I  
want to monitor everyone's changes easily. And since the code of each  
module doesn't interfere with other modules, 'breaking' a revision  
won't stop other developers from working on their source.

Completely agree, apart from the 'trunk' part... it really depends on  
the structure of your repos, it might be the trunk, it might be some  
branches.. :) And note i don't necessarily DISagree with the 'trunk'  
part, just saying it could be either.

Yes, and whether you keep working branches or a working trunk depends  
on how your repository is set up. I prefer to keep working branches,  
allows for easy 'version' management and track-back :)
